Comment on Barabasi, Nature 435, 207 (2005)

Daniel B. Stouffer, R. Dean Malmgren, Luis A. N. Amaral

备注：
This manuscript re-analizes data from Barabasi's paper in Nature, "The origins of bursts and heavy tails in human dynamics", but it should be clear that the same problems are to be found in physics/0510117 and the upcoming Nature advertised in Barabasi's web site concerning the correspondence of Einstein and Darwin

摘要：

在最近的一封信中，Barabasi声称许多人类活动的动力学是无标度的[1]。他特别报告说，单个用户发送的连续电子邮件之间的时间间隔τ和电子邮件回复的时间延迟的概率分布遵循指数为-1的幂律，并提出了一个优先级排队过程来解释人类活动的突发性。在这里，我们定量地证明，报告的幂律分布仅仅是一个人工制品的经验数据的分析，所提出的模型是不代表的电子邮件通信模式。

英文摘要：

In a recent letter, Barabasi claims that the dynamics of a number of human activities are scale-free [1]. He specifically reports that the probability distribution of time intervals tau between consecutive e-mails sent by a single user and time delays for e-mail replies follow a power-law with an exponent -1, and proposes a priority-queuing process as an explanation of the bursty nature of human activity. Here, we quantitatively demonstrate that the reported power-law distributions are solely an artifact of the analysis of the empirical data and that the proposed model is not representative of e-mail communication patterns.
